A sore throat that won't go away can be frustrating, especially if it comes with pain, fever, or trouble swallowing. Strep throat is a bacterial infection that can spread easily and cause discomfort. Knowing how it spreads, who is most at risk, and when to take action can help. This self-assessment quiz will guide you through key facts.

What Causes Strep Throat?

Strep throat is caused by bacteria called Streptococcus pyogenes. It spreads through tiny droplets released in the air when an infected person coughs, sneezes, or shares food and drinks. Touching contaminated surfaces and then touching your face can also increase the risk of getting infected.

Can Strep Throat Spread?

Yes, strep throat is highly contagious. It spreads easily in schools, workplaces, and households. People with strep throat can pass it to others even before symptoms appear. Washing hands and avoiding close contact can help lower the risk of getting sick.

How Common Is Strep Throat?

Strep throat is most common in children and teens, but can affect anyone. It tends to spread more during colder months when people spend more time indoors and confined spaces. While sore throats have many causes, strep infection accounts for a large number of throat illnesses.

When Should You Be Concerned?

A sore throat from a cold usually gets better on its own, but strep throat may need treatment. If you have a sudden, severe sore throat with fever, swollen lumps on the neck, or white patches in the throat, it could be strep infection.
